Impact of a Surgical Approach on Endometrial Cancer Survival According to ESMO/ESGO Risk Classification: A...

Background: Following the results of the Laparoscopic Approach to Carcinoma of the Cervix (LACC) trial, doubts have arisen about the safety of laparoscopy in the treatment of endometrial cancer. Methods: A retrospective multicenter cohort study which included all endometrial cancer (EC) patients who underwent a hysterectomy in Emilia Romagna hospitals from 2000 to 2019. All cases were revised and classified according to the 2009 International Federation of Gynaecology and Obstetrics (FIGO) staging system. The different impacts of the surgical approach on survival were stratified according to the recurrence risk from the 2016 European Society for Medical Oncology (ESMO)-European Society of Gynaecological Oncology (ESGO) classification system. The clinical characteristics and oncological outcome of patients treated by laparoscopy were compared with those treated by laparotomy. Results: A total of 2402 EC patients were included in the study. The use of laparoscopy has increased over the years, reaching 81% of procedures in 2019. Laparoscopy reduced complications and hospital stay. Laparoscopy was preferred to treat low, intermediate, and intermediate/high-risk patients. Laparoscopy showed no adverse effects on overall survival (OS) in any recurrence risk class. Particularly in high-risk EC patients, laparoscopy was associated with an increased OS in comparison with women treated by laparotomy regardless of the use of adjuvant therapy. Conclusions: Laparoscopy should always be chosen to treat EC of any risk class. The goal is to ensure correct treatment and oncological safety regardless of the surgical approach.
